Here is Scorpion default skin for his base skin. Depending on what program you use, there will be differences. In my case i used the alpha from NORM DDS for his alpha in COLOR DDS to get a quick diffuse. Try it out and see what happens. GL

I have adobe ps and can't get this result. does it make a difference if the textures are in tga or dds? i'm using tga.

My process is I open all DDS images of color, norm, rma, id, and tone. I take the alpha from NORM and replace the COLOR version so I have a quick diffuse. I then copy the ID DDS as a layer to COLOR DDS, I use the ID as a color palette to fill in the colors so I don’t miss anything. Then I just save it as a PSD. Then I use Lightwave 3D for all my renders etc. This is one of a few ways to approach this.
